SPARE-TIRE CARRIER,

Application filed. October 10, Seria1No. G1-,734:

This invention relates to spare tire carriers "for vehicles. Theinvention has for its object to provide means on the Vehicle cooperatingwith means onthe tire carrying" rim, which will make 'it 'possible ,toreadily place aspare tire in position. It is I the particular object ofthe invention to provide means to prevent the tire" carrying rim" frombeing rotated circumferentially and removed.

The invention consists in the inter-engagement of-lugs-onthe rim withgrooves vonthe carrier and the provision in such an arrangement oflocking means to prevent circumferential rotation of the rim, whichwould release the lugs from the grooves and permit the removal of thetire and rim.

Theinvention will be best understood by referenceto the accompanyingdrawing in which Figure 1 is a rear elevation of carrier and rim.

Figure 2, is a section on line 2-2 of Figure 1.

Figure 3,is a section on line 8-3 of Figure 2.

Referring to the drawings, reference character 1 represents a cross barwhich 1s mounted in any convenient way upon the preferably at its rearend. Clamped near the ends of bar 1. are upwardly and rearwardlyextended arms 3.

r The endof each of these arms is provided with two grooves 4, one foran inwardly located rim and one for an outwardly located' rim. Extendingrearwardly from the central part of the cross bar 1, is a horizontallydirected arm 5. To the outer end of this latter arm and to the upperends of arms 3, is secured a generally triangularly shaped member '7.Fixed to the rear surface of this member 7 atabout its lower apex, is asleeve 9, carrying for vertical reciprocation, rod member 11, arrangedto be securedin adjusted positions in the sleeve.

The rod 11, carries at its lower end a double slotted plate member 13,best shown by Figure 3. Y

The carrier is intended foru'se with tire carrying rims having aplurality of inwardly directed lugs 15 located adjacent one side of therim. These lugs, it will be seen may slide through the grooves of thearms. When the lugs are within the grooves the rim is-gheld fromremoval, but, turned suhiciently to disengage the lugs :from-the groovesthe rim may be removed. To prevent suclr disengagement bycircumferential turnlng, either {as a result of accident or by maliciousintent, locking means is obtained by the engagement of lugs in the slotsof plate 13. Thelugs are in such position that when the upperlugs arewith-in the grooves the lower luglies opposite the slot of'gthe slottedplate. If now the rod member is reciprocated sufficiently to engage thelower lug in the slot, the rim is held by the two grooves and the singleslot and cannot be turned because the lower lug would engage one of theend walls of the slot;

When two tires are carried, the rims are arrangedwith their sidescarrying the lugs facing each other, as in Figure 2. If a single sparetire is being carried, a preferred arrangement is obtained by placingthe rim so that its flat faceextends across the car-' rier instead ofaway from the carrier. See dotted lines in Figure 2 the lugs engagingone set of grooves and the slot, as will be understood. By thearrangement described a very simple and eii'ective means is pro videdfor holding one or two spare tires. It is easily clamped in position andwhen so secured it cannot'be released by a turning movement of the rim.

WVhat I claim and desire to protect by Letters Patent is:

1. Spare tire carrying means for vehicles comprising a rim havinginwardly'and radially projecting lugs and a carrier having a pluralityof cooperating grooves, one of which is closed at its ends to form aslot to thereby prevent a circumferential turning of the rim.

2. Means for carrying a spare tire comprising a rim, radial lugs on therim, a fixed frame having grooves through which the lugs may slide and aradially reciprocating member carrying a slotted plate the slot havingend walls to engage, one of said lugs and thereby preventcircumferential movement of said rim.

3. Spare tire carrying means comprising a rim having a plurality. ofinwardly and radially projecting lugs, a cross bar for attachment to thevehicle, upwardly and rearwardly directed arms carried by the cross bar,a substantially triangular frame carrim having); a ring portion and amarginal flange, the ring portion having rironm'toruntiill npaoociradial lugs ai'ijarent ono side a frame nimnbor baring ciromni croniiailrpaooi'l holding means, one of said holding moans having aloha sparedaxially to an extent: rommonniirate with the Width of aairi ring,whereby the rim may be soi-uroil in ono or two positions, rithorprojecting away iii-om the holding moans to accommo- (into a second rimor lying; liar, againnt the holding means, tho aamo big; anti slotcooperating to prevent oironinferential moromoot oi" the rim in oarh oisaid. positions of the rim.
